Some version control systems (f.e. Perforce) keep files read-only and you have to check them out before editing. Currently mobile notifications don't handle this and modifying settings will fail.
This PR makes it use Editor API to make file editable in a VCS friendly way.
A small unrelated change is Android SDK requirement to compile the code.
